Question

Matt has already sold $72 worth of tickets to the benefit concert. He had 6 tickets left to sell at $9 per ticket.

Answer 1

Answer:

$f(t)=9t+72$

Step-by-step explanation:

Matt has already sold $72 worth of tickets to the benefit concert.

He had 6 tickets left to sell at $9 per ticket.

We can write the function of total amount earned as:

$f(t)=9t+72$ ; where t = 6

f(t) represents the total amount earned by Matt by selling all tickets.

So total amount will be :$9(6)+72=126$ dollars

Answer 2

What is the question? 
Matt sold 8 tickets at $9 each. 8 tickets x $9= $72
He still has 6 tickets left. 6 x $9=$54 
Total tickets=14
Total amount of money when he is done selling the rest of the tickets is $126
